A LIST OF FLUID EXTRACTS, 



4 coentlt introduced into veterinary pbaotioa 



By G. H. DADD, v. S., 



with instri>ction regarding their action, aot) 

 the quanxrry to be administered. 



THE introduction of medicines, in the form of Flijid Ex- 

 •rRACTS, for the treatment of diseases incidental to domestic 

 animals is considered a very great improvement over the old 

 method of drenching by the pint or quart, to the great disgust of 

 the patient as well as the practitioner, and the great danger attend- 

 ing the administration of a large quanty of fluid which was neces- 

 Bftry wh 3n crude materials were used. In the use of fluid extracts 

 all dan[;er ib obviated and much labor saved, for the doses are 

 quite email, rarely exceeding one fluid ounce. This can be merely 

 placed ofl the tongue, the animal's head being slightly elevated, 

 and he sArallows it without any difficulty or resistance. 



The fluid extracts bear an exact relation to the crude materials — • 

 that is, ouQce for ounce — yet, from a variety of circumstances, they 

 may vary slightly from this standard. It is, however, the inten- 

 tion of the manufacturer to completely exhaust the active principle 

 of the cruda material and render the medicine uniform in strength. 

 The fluid extracts used by the author are manufactured by Messrs. 

 Garrison .S Co., manufacturing chemists, of Chicago. They con- 

 duct their ev'aporations at a very low teni|)erature, by means of an 

 improved st-^ara bath, and use only select drugs, thereby prevent- 

 mg the possibility of adulteration. I have used large quantities 

 of medicine n^nufactured by the above-named firm, and find them
